Hi, I am Elroy Chua!
I'm passionate about user experience and software development, eager to leverage new technologies for positive change and problem-solving. With over a year of hands-on experience in PostgreSQL, Express.js, React & Node.js with TypeScript. Let's connect!
My background in Spatial Design at Nanyang Polytechnic introduced me to design thinking, architectural technologies, and UX concepts. During National Service, I delved into UX design and web development. I recently completed my Bachelor's in Computer Science with Distinction, specializing in Big Data at the University of Wollongong. I also engage in hackathons, interest groups, and have work experience as a Full Stack Software Developer Intern at GetPaid and have grown from a Full Stack Software Developer Intern to my current role as Associate Software Engineer at Ensign InfoSecurity. I find meaning volunteering at a local church, participating in feeding programs for underprivileged children in the Philippines 🇵ðŸ‡, playing guitar 🎸 with over 6 years of live playing experience, acting in commercials 🎬, and travelling.
